(Dipper & Mabes be like 15 now!) When the twins come back to Gravity Falls for the Summer. It's Dipper's first time back since the first Summer, but not Mabel's. Every one is surprised to find that their favorite awkward little nerd has become a hot, cool, and hair obsessed bad-boy. Mabel is still Mabel, But Dipper is no longer Dipper. He doesn't even go by his old nick-name anymore, now he's just Michael Pines instead of "Michael Pines, but goes by Dipper". Did I mention... Now he does drugs?
